Of course, for convenience, we can also use aliases like alias ll= ' ls-l--color=auto '

, define an alias:

<span style= "FONT-SIZE:18PX;"  >[[email protected] ~]$ alias ll= ' LS-LHF--color=auto ' [[email protected] ~]$ ll total dosage 1.1gdrwxrwxr-x.  2 Doctor Doctor 4.0K January 10:23 documents/-rw-r-----.  1 Doctor doctor 701M December 21:51 far123-xp-2014.5c.isodrwxr-xr-x.  4 Doctor Doctor 4.0K November 16:00 hadoop/drwxrwxr-x. 6 Doctor doctor 4.0K December 22:04 hbaserootdir/drwxrwxr-x.

I am here to cover the system alias, do not appear in the shell syntax space, note.

2. How to show hidden files, general configuration The system commands such as JDK are defined in . bash_profile. BASHRC .

You may think of ls-a, but he also shows other directories.

You can use ls-d. * Show only these hidden directories.

-D,--directory

lists directory names like other files, rather than listing their contents.
